The PCB surface finish forms a critical interface between the component to be assembled and the bare printed circuit board.
The surface finish has two essential functions:
- To protect the exposed copper circuitry.
- To provide a solderable surface when assembling (soldering) the components to the board.
Most surface finishes are considered SMOBC (Solder Mask Over Bare Copper).
